ABSTRACT
Recurrent urinary tract infections (R-UTI) are common among women even though they generally have a normal urinary tract. Women with R-UTI have an increased susceptibility to vaginal colonization with uropathogens due to a greater propensity for them to adhere to their epithelial cells. Risk factors include frequent sexual intercourse, spermicide use, first UTI at an early age and maternal history of UTI. Prevention of recurrences can be done with low-dose continuous antimicrobial prophylaxis or with post-coital antimicrobial prophylaxis, a method that may be more efficient and acceptable. Estrogen replacement therapy using a vaginal administration in postmenopausal women is also effective in preventing R-UTI. The vaginal vaccine only diminishes percentage of women with Escherichia coli UTI. The oral vaccine reduces R-UTI with inferior results than antimicrobial prophylaxis; Cranberry intake shows some evidence in favor, although further trials are needed. Finally R-UTI can also be effectively managed with self-start antimicrobial therapy.
RESUMEN
La infección urinaria recurrente (ITU-R) es común en mujeres que generalmente no presentan alteraciones del tracto urinario, pero que tienen una mayor predisposición a la colonización vaginal por uropa-tógenos que se adhieren más ávidamente a sus células epiteliales. Las relaciones sexuales frecuentes, el uso de espermicidas, el antecedente de ITU a corta edad y la historia materna de ITU son factores de riesgo. La prevención de la recurrencia puede hacerse con profilaxis antimicrobiana continua a dosis baja o post-coital. La terapia de reemplazo estrogénico en la mujer post-menopáusica es efectiva en prevenir ITU-R, recomendándose su uso vía vaginal. La vacuna vaginal sólo disminuye el porcentaje de pacientes con ITU por Escherichia coli; la vacuna oral disminuye las ITU-R aunque con resultados inferiores a la profilaxis antimicrobiana. La ingesta de arándano rojo muestra alguna evidencia a favor, aunque insuficiente. Finalmente, la ITU-R también puede manejarse con terapia antimicrobiana iniciada por la paciente.
